In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will describe the technical solutions of the embodiments of the present application clearly, completely, and clearly with reference to the drawings in the embodiments of the present application. The described embodiments are some but not all embodiments of the present application. All other embodiments obtained based on the embodiments in the present application shall fall within the scope of protection of the present application.

Regarding the technical problem that the above-mentioned conventional innovative service processing method can only play a remedial effect, and it cannot assess the risk of innovative service in advance, the present application is based on blockchain. A service information processing method, apparatus and readable storage medium are provided.

It should be noted that the blockchain-based service information processing method, device and readable storage medium according to the present application can be applied to any service risk assessment scene.

First, the nouns relating to the present application are interpreted.
Blockchain: Blockchain is a new application mode of computer technology such as distributed data storage, ad-hoc mode transmission, consensus mechanism, and cryptographic algorithm.

FIG. 1 is a flow schematic diagram of a blockchain-based service information processing method according to Embodiment 1 of the present application, as shown in FIG. 1, the method includes the following steps.

Step 101, the monitoring node sends a voting request on the blockchain. Here, the voting request includes service information and voting options, and the blockchain includes the monitoring node and at least one evaluation node.

The execution subject of this embodiment is a monitoring node, and the monitoring node may be a user terminal or a server. In order to assess the risk of a service, it is first necessary to establish a blockchain, the blockchain including the monitoring node and at least one evaluation node, where the monitoring node is i.e. a service monitoring mechanism, an evaluation node may be a group of people participating in a service evaluation vote. Specifically, the watcher node may distribute a voting request on the blockchain, where the voting request may include service information and voting options for innovative services for which risk assessment needs to be performed, e.g. , the voting option may include a "yes" or "no", excellent/good/fair/bad or any scoring mechanism, whereby the evaluation node knows the voting rules based on the voting option. can do. In addition, the voting request may further include a reward total and a reward rule corresponding to the voting request, a voting request deadline time, and a monitoring configuration identifier for initiating the voting request, whereby issuing a reward may result in more Many evaluation nodes can be rewarded to vote. The total number of rewards, reward rules, and voting request deadline are pre-written in the smart contract.

It should be noted that the above innovative service may be service information in any field, for example, it may be an innovative financial service, and the present application is not limited here.

Further, according to any of the embodiments above, the voting request is sent after the monitoring node detects the creation of a new service.

In this embodiment, the voting request is sent to the blockchain after the monitoring node detects the creation of a new service. Specifically, the monitoring node may detect whether there is currently a new service generation by a preset detection method, for example, periodically detect whether there is currently a new service APP online. Alternatively, any detection scheme may be adopted to realize detection for new services, and the present application is not limited here. In addition, after the monitoring node detects the emergence of a new service, it will immediately send the corresponding voting request in the blockchain, thereby effectively avoiding the loss caused to the user by the monitoring of the service in time. .

Step 102, after a preset time elapses, the monitoring node generates a block based on all voting results verified by the verification node, uploads the block to the blockchain, and the verification node It is obtained by election from at least one evaluation node.

In this embodiment, after receiving the voting request, all evaluation nodes in the blockchain may vote based on the voting request and broadcast the voting results to the blockchain. In order to verify the correctness of the voting results, it is necessary to elect at least one verification node to verify the voting results. It should be noted that the smart contract is pre-written with a pre-set time when the voting is already closed, so that after the pre-set time, the monitoring node will obtain all the voting results verified by the verification node and A block may be generated based on the voting results and the block may be linked to the blockchain.

Step 103, the monitoring node decides whether to enter the risk evaluation flow based on all the voting results.

In this embodiment, the monitoring node generates a block based on the verified voting results, links the block to the blockchain, and then decides whether to evaluate the risk of the service based on the voting information in the block. may decide. Taking the practical application as an example, there are currently 100 voting results, of which 80 are "excellent", 10 are "good", and 6 are "average". , and if the four evaluation results are "bad", most of the evaluations are moderate or higher, so it can be determined that the service risk is low at this time. A risk assessment needs to be performed. In a possible mode, the voting results are displayed in the form of statistical charts so that the observer can more intuitively decide whether to assess the risk of the service or not. Further, after determining the risk of the service, the service may be processed with monitoring measures corresponding to the risk further based on the risk of the service.

In the conventional technology, due to cost and other factors, the monitoring organization cannot determine problems that may occur in innovative services of financial institutions through large-scale research. When assessing the impact of the outbreak, there is no rational and scientific mechanism, and it can only be used as the basis for collecting and evaluating data and information by conventional technical units, and taking monitoring measures. , from the angle of information acquisition, it is very limited and has obvious limitations. The above method can be adopted to vote by multiple evaluation nodes, thereby obtaining a large amount of evaluation information, and effectively solving the limitation of the monitoring method in the prior art.

In addition, since the monitoring measures have a strong binding effect on the service activities of financial institutions, once they are implemented, the effects will appear immediately, the consequences caused by them may be rapid, and the impacts generated by them can also be estimated. In addition, the “extremism” of the measures may hurt financial innovation, and it will have the opposite effect by putting pressure on financial market information. The above method can effectively avoid the radicalness of the conventional monitoring method by adopting a risk-based monitoring method for different service risks.

The method for information processing a service based on a blockchain according to the present embodiment establishes a blockchain so that when a monitoring node detects the creation of a new service, it simultaneously distributes a voting request for risk assessment of the service in the blockchain, Generate a block based on all vote results verified by the verification node, and perform risk assessment based on all vote results in that block, thereby quickly deciding whether to assess the risk of the service. to avoid causing loss to the user.

Further, based on any of the above embodiments, the watcher node generates blocks based on all vote results verified by verification nodes, and after uploading the blocks to the blockchain, the preset issuing rewards to all evaluation nodes participating in voting based on the smart contract.

In this embodiment, rules for reward issuance may be pre-written in smart contracts to encourage evaluation nodes to actively vote on voting requests. Therefore, after the monitoring node generates blocks based on all voting results verified by validating nodes and uploads the blocks to the blockchain, all evaluation nodes participate in voting based on the preset smart contract. may issue rewards to

The blockchain-based service information processing method according to the present embodiment issues rewards to all evaluation nodes participating in voting based on a preset smart contract, so that the evaluation nodes actively respond to voting requests. and provide a basis for assessing service risk.

It is the rating node that can be obtained whose next voting option is 'good', and the lowest reward is obtained for the rating node whose voting option is 'bad'. Specifically, the calculation of the reward can be realized by Equations 1 to 3.

In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will describe the technical solutions of the embodiments of the present application clearly, completely, and clearly with reference to the drawings in the embodiments of the present application. The described embodiments are some but not all embodiments of the present application. All other embodiments obtained based on the embodiments in the present application shall fall within the scope of protection of the present application.

Regarding the technical problem that the above-mentioned conventional innovative service processing method can only play a remedial effect, and it cannot assess the risk of innovative service in advance, the present application is based on blockchain. A service information processing method, apparatus and readable storage medium are provided.

It should be noted that the blockchain-based service information processing method, device and readable storage medium according to the present application can be applied to any service risk assessment scene.

First, the nouns relating to the present application are interpreted.
Blockchain: Blockchain is a new application mode of computer technology such as distributed data storage, ad-hoc mode transmission, consensus mechanism, and cryptographic algorithm.

FIG. 1 is a flow schematic diagram of a blockchain-based service information processing method according to Embodiment 1 of the present application, as shown in FIG. 1, the method includes the following steps.

Step 101, the monitoring node sends a voting request on the blockchain. Here, the voting request includes service information and voting options, and the blockchain includes the monitoring node and at least one evaluation node.

The execution subject of this embodiment is a monitoring node, and the monitoring node may be a user terminal or a server. In order to assess the risk of a service, it is first necessary to establish a blockchain, the blockchain including the monitoring node and at least one evaluation node, where the monitoring node is i.e. a service monitoring mechanism, an evaluation node may be a group of people participating in a service evaluation vote. Specifically, the watcher node may distribute a voting request on the blockchain, where the voting request may include service information and voting options for innovative services for which risk assessment needs to be performed, e.g. , the voting option may include a "yes" or "no", excellent/good/fair/bad or any scoring mechanism, whereby the evaluation nodes know the voting rules based on the voting option. can be made In addition, the voting request may further include a reward total and a reward rule corresponding to the voting request, a voting request deadline time, and a monitoring configuration identifier for initiating the voting request, whereby issuing a reward may result in more Many evaluation nodes can be rewarded to vote. The total number of rewards, reward rules, and voting request deadline are pre-written in the smart contract.

It should be noted that the above innovative service may be a service in any field, for example, it may be a financial innovative service, and the present application is not limited here.

Further, according to any of the embodiments above, the voting request is sent after the monitoring node detects the creation of a new service.

In this embodiment, the voting request is sent to the blockchain after the monitoring node detects the creation of a new service. Specifically, the monitoring node may detect whether there is currently a new service generation by a preset detection method, for example, periodically detect whether there is currently a new service APP online. Alternatively, any detection scheme may be adopted to realize detection for new services, and the present application is not limited here. In addition, after the monitoring node detects the emergence of a new service, it will immediately send the corresponding voting request in the blockchain, thereby effectively avoiding the loss caused to the user by the monitoring of the service in time. .

Step 102, after a preset time elapses, the monitoring node generates a block based on all voting results verified by the verification node, uploads the block to the blockchain, and the verification node It is obtained by election from at least one evaluation node.

In this embodiment, after receiving the voting request, all evaluation nodes in the blockchain may vote based on the voting request and broadcast the voting results to the blockchain. In order to verify the correctness of the voting results, it is necessary to elect at least one verification node to verify the voting results. It should be noted that the smart contract is pre-written with a pre-set time when the voting is already closed, so that after the pre-set time, the monitoring node will obtain all the voting results verified by the verification node and A block may be generated based on the voting results and the block may be linked to the blockchain.

Step 103, the monitoring node decides whether to enter the risk evaluation flow based on all the voting results.

In this embodiment, the monitoring node generates a block based on the verified voting results, links the block to the blockchain, and then decides whether to evaluate the risk of the service based on the voting information in the block. may decide. Taking practical application as an example, there are currently 100 voting results, of which 80 voting results are "excellent", 10 voting results are "good", and 6 voting results are "normal". , and if the four voting results are "bad", most of the evaluations are moderate or higher, so it can be determined that the service risk is low at this time. A risk assessment needs to be performed. In a possible mode, the voting results are displayed in the form of statistical charts so that the observer can more intuitively decide whether to assess the risk of the service or not. Further, after determining the risk of the service, the service may be processed with monitoring measures corresponding to the risk further based on the risk of the service.

In the conventional technology, due to cost and other factors, the monitoring organization cannot determine problems that may occur in innovative services of financial institutions through large-scale research. When assessing the impact of the outbreak, there is no rational and scientific mechanism, and it can only be used as the basis for collecting and evaluating data and information by conventional technical units, and taking monitoring measures. , from the angle of information acquisition, it is very limited and has obvious limitations. The above method can be adopted to vote by multiple evaluation nodes, thereby obtaining a large amount of evaluation information, and effectively solving the limitation of the monitoring method in the prior art.

In addition, since the monitoring measures have a strong binding effect on the service activities of financial institutions, once they are implemented, the effects will appear immediately, the consequences caused by them may be rapid, and the impacts generated by them can also be estimated. In addition, the “extremism” of the measures may hurt financial innovation, and it will have the opposite effect by putting pressure on financial market information. The above method can effectively avoid the radicalness of the conventional monitoring method by adopting a risk-based monitoring method for different service risks.

The method for information processing a service based on a blockchain according to the present embodiment establishes a blockchain so that when a monitoring node detects the creation of a new service, it simultaneously distributes a voting request for risk assessment of the service in the blockchain, Generate a block based on all vote results verified by the verification node, and perform risk assessment based on all vote results in that block, thereby quickly deciding whether to assess the risk of the service. to avoid causing loss to the user.

Further, based on any of the above embodiments, the watcher node generates blocks based on all vote results verified by verification nodes, and after uploading the blocks to the blockchain, the preset issuing rewards to all evaluation nodes participating in voting based on the smart contract.

In this embodiment, rules for reward issuance may be pre-written in smart contracts to encourage evaluation nodes to actively vote on voting requests. Therefore, after the monitoring node generates blocks based on all voting results verified by validating nodes and uploads the blocks to the blockchain, all evaluation nodes participate in voting based on the preset smart contract. may issue rewards to

The blockchain-based service information processing method according to the present embodiment issues rewards to all evaluation nodes participating in voting based on a preset smart contract, so that the evaluation nodes actively respond to voting requests. and provide a basis for assessing service risk.

Step 201, determining the optimal voting option with the highest number of votes among all the voting results.
Step 202, issuing a reward to the evaluation node based on the proximity of the voting option of the evaluation node and the best voting option, where the best voting option corresponds to the highest reward.
